Identification of nitroso compounds from biotransformation of 2,4-dinitrotoluene
Disposal of ammunition wastewater is difficult and has caused environmental concern. Compounds common in ammunition effluents are resistant to biological treatment processes such as the activated sludge system. Low levels of these compounds are also toxic to various forms of life, including fish. The intermediates of microbial transformation of 2,4-dinitrotoluene by a mixed bacterial culture derived from activated sludge were identified as 2-amino-4-nitrotoluene, 4-amino-2-nitrotoluene, 2-nitroso-4-nitrotoluene, and 4-nitroso-2-nitrotoluene. The biotransformation of 2,4-dinitrotoluene occurred only under anaerobic conditions with an exogenous carbon source. The two nitroso compounds were unstable and could be observed only at the early stage of 2,4-dinitrotoluene anaerobic biotransformation.
